Electronic zero air loss drains GCNL10 and GCNL100
Draining the moisture from compressed air systems ensures less downtime and damage due to rust and scale. Gardner Denver drains are designed for long life and require minimum maintenance. They are critical components in the quest for system efficiency and reliability. When a drain fails to discharge the condensate, the condensate can carry over into the system, causing a build-up of contaminants in dryers, receivers and filters. On multiple stage compressors, moisture carryover from the intercooler may allow liquid into the next stage, causing premature wear and a potentially catastrophic failure.
Electronic zero air loss drain with alarm feature
The GCNL10 removes all types of condensate from compressed air systems with air flow up to 10 3/min without the loss of compressed air while the GCNL100 up to 100 m3/min.
Product features
The GCNL10 is an electronic zero air loss drains suitable for smaller compressed air applications. It offers an incredibly compact solution with unrivalled installation versatility and reliability. Typical draining applications include fridge dryers and filters. To further simplify the installation in restrictive height conditions, a side inlet adapter is available.
The GCNL100 offers a rapid pay-back period due to the zero air loss feature and energy saving features. The compact and robust industrial housing, 2/2 way direct acting valve with a large orifice, alarm feature and the integrated mesh strainer make the GCNL100 and GCNL100-HP highly reliable draining solutions. Equipped with a digital, LED illuminated, sight-port/level indicator showing you the condensate level inside the reservoir and enabling you to monitor the operation, even in poor lit places.
